El Mayimbe is letting us down. This seems like a good time to point out that the most recent IM3 trailer appears to have proven every single scoop Latino Review had about that movie last year to be correct, except for the Stan Lee cameo, which remains to be seen.
Latino Review's IM3 Exclusives from last year:

-Return of the Ten Rings
-Extremis
-Kingsley is the Mandarin (which Marvel was denying at the time), but that he is really 2nd fiddle to Killian.
-Tony Stark fighting the Mandarin with an army of unmanned suits.
-The "Iron Patriot" really being War Machine decked out.
-Stan's cameo as a beauty pageant judge.

All essentially confirmed by the new trailer except the blacked out stuff, and one of those was pretty much confirmed in an interview with James Badge Dale.

Also, the AICN scoop about Nova further validates what LR first reported when they broke the scoop about GotG in the first place:

All of those exclusives were reported by Da7e at LR, who has proven himself quite consistently to be a reputable source. El Mayimbe, less so. But I think it's silly to write off the whole site's credibility - when they've continually provided more accurate Marvel scoops than anyone - because one obnoxious guy there has a hit-and-miss track record.

I am writing off the whole site's credibility after El Mayimbe trolled SHH with hot garbage.
